INTRODUCTION
The Telephone Interface allows you to use home phones to receive and answer calls
from the automatic entry system and you can also forward them externally via a telephone
line.
Therefor the (internal) home phone can receive calls from the street panel and from an
external line (telephone line). The latter always has the priority over the street panel in
case of receiving calls simultaneously and before having answered it.
The key feature of this Telephone Interface is that a single reference works for analogic
4+N and VDS installations.
Other new features include:
•Audio level settings from the phone.
•The chance of changing the conversation mode to half-duplex or simplex mode
dynamically.
• Remote access from an external line (protected by a PIN code), to all functions
available to internal telephones: activation of the relay, programming, connection
to the street panel, door open....etc.
• Call forward. If there is no response from the internal telephones, it is forwarded to
a second telephone when the first one does not answer.
• Configurable time parameters.
• Compatible with advanced telephone services (the use of * and #).
• The use of pause in the external call number.
• External signal of forward mode (open collector output).
Notice: The maximum number of telephones connected to the telephone interface that
guarantees the proper operation is 4 (just like with the telephone companies).
The interface accepts different configurations and working modes. These are the available
modes:
o4+N System: In this mode, the interface works with the analogic street panel system
where the call is generated via a single cable. In 4+n there is only one operating
mode:
- Single Call (SCM). The interface acts as a telephone terminal that responds to a
single call from the street panels.
oVDS System: In thismode,theinterfaceworks with the VDS system, where itperforms
the call via a command. VDS has the option to work in two different operating modes:
- Single Call (SCM). The interface acts as a telephone terminal that responds to a
single call from the entry panels.
- Multiple Call (MCM). The interface acts as a gateway between the VDS system
and a telephone system (telephone switchboard or a telephone line), converting
the VDS calls to telephone numbers, that is, multi-calling, to make different calls
to different extensions or telephones relative to the VDS call generated on the
entry panel. This way you can make calls to different extensions in an office from
the entry panel, not just to one, like in the previous models.

- This must be installed on the interior, within an installations box.
- The telephone lines do not need to follow the polarity.
- In ADSL lines they must be connected after the right filter.
- On 4+N installations you can not share the street panel's power when AC. The VDS can
be powered by the bus.
- The telephones connected to the internal line must work with tone dialling.
Capacities and parameters description
The default values are displayed between brackets [ ] .
•Pin Code: only one, [0000]. This is used for accessing the remote site via the external
line.
• VDS Call num.: 001..199 [1] programmed. This is used in a single call (SCM) to
respond to the call from the street panel.
• Call forward numbers of a single call (SCM):
- Number: 2 (001-002).
- Length: 16 digits.
- [Not Defined].
• Call forward numbers of a multiple call (SCM):
- Number: 199 (001..199).
- Length: maximum of 16 digits (telephone numbers).
- [Not Defined].
• Dooropeningtime(DOT/DoorOpeningTime):01 .. 99" [04]. Time for the activation of the
4+N door open.
• RingCallTime(RCT/RingCallTime):01..99" [30]. Maximum time that the interface waits
for the call from the street panel to be answered. In VDS, even if a time programmed
is greater than 30", the street panel will cut the call at this time.
• DivertDelayTime(DDT/DivertDelayTime):01..99"[1].Thedelayfortheinteriortelephone
to respond to a call from the street panel before forwarding it to an external telephone.
Note: In VDS, this must be a maximum of 30" and less time than the duration of the
call (RCT).
• Auxiliary Relay Time (ART / Auxiliary RelayTime):00..99" [08]. The time during which the
auxiliary relay remains activated. The value 00 means bi-stable mode.
• ConversationTime(CT/ConversationTime):01..99" [90]. Conversation time. In VDS, the
conversation time must be set to 90 seconds to coincide with the VDS panel values.
Notes:
- For the interface to be operative after connecting the power, wait 10 seconds, which
isthetimeitneedstodetectif there is an external telephone line, otherwise it generates
the power from the internal line.
- Call priorities: the call from the external telephone line always has priority. That is, if
you receive an external call and before hanging up you receive a call from the street
panel, the latter is not notified. On the other hand, if you are on a call from the street
panel, and you receive a call from the external line, the former is cancelled and the
latter is received.

• Ring cadence (RC / Ring Cadence):1..9" [3]. Time interval between two consecutive call
tones when calling from a street panel.
• Conversationmodewiththeentrypanel:[Full-Duplex (FD)].Available audio modes: Full-
Duplex, Half-Duplex, Simplex.
• Conversation modes with forwarded calls:[Full-Duplex (FD)]. Available audio modes:
Full-Duplex, Half-Duplex, Simplex.
Notes:
Audio modes:
-Full Duplex (FD): The input audio channels (panel to telephone) and output audio
(telephone to panel) are opened simultaneously.
- Half Duplex (HD): The input and output audio channels are open, but only once
each, changing automatically from one function to another relative to the audio
level. The output channel has priority.
- Simplex (S): Only one audio channel is active each time. The switch is performed
manually. The output channel is open by default.
CONFIGURATION

- The use in other non-conventional installations:
• The Fermax telephone interface behaves the same way that a conventional analogic
telephone does, so it will work properly in any telephone installation in which you can
connect a telephone to, like those connected to conventional public networks.
- The use on telephone switchboards:
• This interface may be incompatible with some types of telephone switchboards (ask
the switchboard manufacturer).
INSTALLATION DIAGRAMS
In order to obtain optimal performance of the Telephone Interface and minimise external
interferences that may be produced (network noise, radio electric interferences... etc.) we
recommend:
- On 4+N installations you can not share the street panel's power when AC. The VDS can
be powered by the bus.
- The telephone pair and electronic entry panel cables transport audio signals that are
sensitive to interferences, so we recommend not placing it near noise made from motors
or industrial machinery or electric wiring.

Description of functions
• Standby.
Default status. See the available options for Standby mode in the quick guide.
Notes on some of the functions of the quick guide:
- On the call to the VDS Reception you must hang up the phone after dialling *4 in order
to receive this call.
- In the programming access you use the # key and on the other functions you use the
* key in combination with a number, so you must know that there is a time limit of 3
seconds after picking-up the phone during which the * and # tone do not transmit via
the abandoned line in order to avoid conflicts with the special functions reserved for
the telephone company or special telephone numbers (bank, etc...). If you want to
use these keys, in order to use the commands on the interface you must press * or #
before this time. This time limit is refreshed every time you press a * or #.
• Reception of the call from the entry panel as a single call (SCM).
If you receive a call from the entry panel, the interface will act as an electronic door
entry system telephone, responding to a single call, performed on the call line (4 + N)
or through the programmed call code (VDS). The ring tone is generated in all interior
telephones.
- if one of the interior telephones answers within the ring call time (RCT), it then
communicates with the panel,
- but if the ring call time (RCT) runs out without a response, then the generation of the
call is stopped and it returns to standby.
- if the Fermax telephone responds to the call during the ring call time (RCT) before
the internal telephones, then the the interface stops calling and returns to standby
(only VDS).
The call tone can be changed to distinguish it from the external call via the programming
menu, see programming Ring Cadence (RC / Ring Cadence). During the conversation
you can open the entrance door, activate an auxiliary relay, adjust the upload audio
level or the duplex conversation mode.
The conversation ends when the telephone hangs up, after the programmed
conversation time or when the exterior panel cuts the conversation (what happens
first).
If during the creation of a ring tone from the entry panel an external call occurs, this
would have priority and generate the corresponding ring tone so that upon picking up
the internal telephone the communication is established with the external line.
• Reception of an external call.
If you receive an external call, (this call is generated by the telephone company when
an external telephone calls), all interior telephones will produce the call tone and one
of them will respond, establishing the normal communication as if there is no interface.
The ring tone is generated by the telephone switchboard or the phone itself (depending
on the models). This function ends when the telephone that responds to the call
hangs-up.

Key Option
* 1 Communication with panel 1 (VDS) or default panel (4+N)
* 2 Communication with panel 2 (VDS)
• Connection with the entry panel.
You can connect from one of the interior telephones to one of the exterior panels
without requiring a previous call, simply by pressing two keys (* N).
If during the external call a call is made from the entry panel, the following occurs:
- If the entry panel calls before picking up the phone, it will not be answered and you
will lose the call (the external call has priority).
- If the entry panel calls during the conversation, it is monitored and you can answer it.
See Call waiting.
If you do not answer the call within the ring call time (RCT) and switch 3 is in ON, the
call is attended to via the interface, which requests the PIN code via a special sound.
If the PIN code is correct the interface will go to remote connection status, but if it is
incorrect, the interface will cancel communication. In the Quick guide see the available
options in Remote mode.
• Communication with the entry panel.
This is the status corresponding to communication between the entry panel and the
interior telephone. During this status audio is established in full-duplex (default), but
you can change it to a different mode (half-duplex or simplex). The different audio
modes are as follows:
- Full Duplex (FD): The upload audio channels (panel to telephone ) and download
audio (telephone to panel) are open simultaneously.
- Half Duplex (HD): The input and output audio channels are open, but only once
each, changing automatically from one function to another relative to the audio
level. The download channel has priority.
-Simplex (S): Only one audio channel is active each time. The switch is done manually
by pressing the 0 key. The download channel is open by default.
You can also adjust the audio level for the upload channel. See the Quick guide for the
options available during the Conversation (status: communication with the entry
panel).
If in communication with the panel you receive an external call, you will hear a special
tone on the interior telephone (two repeated short tones every 5 seconds). The user
can leave the current conversation on hold and attend to the external line and then
resume the conversation with the entry panel. See Call waiting.
See the Quick Guide for the available options during the Conversation (status:
communication with the entry panel)
This function is useful when a previous conversation has expired and the user wants
to recuperate it, or simply to open the door. Once connected, the available options are
described in the Quick guide: The options available during the Conversation (status:
communication with the entry panel).

• Internal Communication (intercommunication).
When there are various internal telephones (maximum 4), you can call from one to
another simply by generating a series of ring tones like that of number N (1...4). This
tone is different from the external line call or the entry panel call. Both the telephone
that started the call and the telephone being called must pick-up the phone and then
start a conversation. The programmed conversation time is also limited as well as
when both phones hang-up.
Key Option
* # N Internal communication, (after dialling you must hang up to generate the N tones).
• Forwarding to an external telephone as a single call (SCM)
If the call from the entrance door is not answered by an interior telephone within the
programmed time, and the forward mode is selected, then the call is transferred to
the programmed external telephone.
The receptor will respond to the call and has the option of conversing, opening the
entrance door, adjusting the audio level or activating an auxiliary relay. You might need
to use special keys to notify the interface that you have hung-up and to hang up in case
that the interface does not recognise these actions. Upon receiving the call if you
hear: beep beep beep, press * to answer and # to end (hang-up) the conversation.
You can program a second telephone number if the first one does not respond to the
call within the programmed time.
In this mode, the available options are described in the Quick guide: Options available
in Conversation mode.
The forward mode is activated from an option on the programming menu or with the
switch connected to the interface. This is supervised via a LED and an output terminal.
For more details on this function see: Key 3 - Forward telephone numbers directory
in Single Call (SCM) and Multiple Call (MCM)
• Generating multiple calls (MCM).
For VDS installations, the interface can manage various calls (up to 199), which
generates different call numbers relative to a programmed table. In this mode you
can call different extensions of a switchboard by connecting an internal line to an
interface's external line, like for an office, so the visitor can select the person who will
receive the call. You can also generate external calls if the subscriber's telephone line
is connected to the external line's connector.
This is a specific case of the telephone system where you connect the entry panel to
the telephone line (through the interface) and the calls are received by the apartments'
individual telephones, which use a company's telephone service.
In this mode, the telephone called has the available options as those described in the
Quick guide: Options available in Conversation mode.
You can forward the calls to a specific extension for a period of time just by activating
the forward mode (sería la dirección VDS grabada en el interface. This is useful when
there is a receptionist that has to filter all of the calls during working hours, but
afterwards the calls must be passed directly to their respective extensions. The
telephone to which it is forwarded to depends on the position in the directory, indicated
in option 0 of the configuration menu.
For more details on this function see: Key 3 - Forward telephone numbers directory
in Single Call (SCM) and Multiple Call (MCM)
